Array Wertsumme basierend auf demselben Schlüssel

Question

ich meine Array-Daten haben, wie unten dargestellt:

Array ( 
    [0] => Array ([name] => Bank BRI [amount] => 0) 
    [1] => Array ([name] => Bank BRI [amount] => 0) 
    [2] => Array ([name] => Bank BCA [amount] => 1412341234) 
    [3] => Array ([name] => Bank CIMB Niaga [amount] => 532532552) 
    [4] => Array ([name] => Bank BRI [amount] => 34534534) 
    [5] => Array ([name] => Bank CIMB Niaga [amount] => 453425243) 
    [6] => Array ([name] => Bank BRI [amount] => 0) 
    [7] => Array ([name] => Bank BNI [amount] => 124124) 
    [8] => Array ([name] => Bank CIMB Niaga [amount] => 352345623) 
    [9] => Array ([name] => Bank BCA [amount] => 23432423) 
    [10] => Array ([name] => Bank Mandiri [amount] => 0) 
    [11] => Array ([name] => Bank BCA [amount] => 0) 
    [12] => Array ([name] => Bank BCA [amount] => 0) 
    [13] => Array ([name] => Bank Permata [amount] => 352352353) 
) 

Wie ‚Menge‘ basiert zusammenzufassen auf demselben ‚Bankname‘.

Meine Daten sollen wie folgt dargestellt:

Bank BRI........... with '*total amount*' 
Bank BCA........... with '*total amount*' 
Bank CIMB NIAGA.... with '*total amount*' 
Bank BNI........... with '*total amount*' 
Bank Mandiri....... with '*total amount*' 
Bank Permata....... with '*total amount*' 

Answer 1

<?php 

// array of bank structure 
$banks = array(); 
$banks[] = array('name'=>'Bank BRI','amount'=>rand()); 
$banks[] = array('name'=>'Bank BRI','amount'=>rand()); 
$banks[] = array('name'=>'Bank BCA','amount'=>rand()); 
$banks[] = array('name'=>'Bank CIMB','amount'=>rand()); 
$banks[] = array('name'=>'Bank BRI','amount'=>rand()); 
$banks[] = array('name'=>'Bank CIMB','amount'=>rand()); 
$banks[] = array('name'=>'Bank BRI','amount'=>rand()); 
$banks[] = array('name'=>'Bank BNI','amount'=>rand()); 
$banks[] = array('name'=>'Bank CIMB','amount'=>rand()); 
$banks[] = array('name'=>'Bank BCA','amount'=>rand()); 
$banks[] = array('name'=>'Bank Mandiri','amount'=>rand()); 
$banks[] = array('name'=>'Bank BCA','amount'=>rand()); 
$banks[] = array('name'=>'Bank BCA','amount'=>rand()); 
$banks[] = array('name'=>'Bank Permata','amount'=>rand()); 

// begin the iteration for grouping bank name and calculate the amount 
$amount = array(); 
foreach($banks as $bank) { 
    $index = bank_exists($bank['name'], $amount); 
    if ($index < 0) { 
     $amount[] = $bank; 
    } 
    else { 
     $amount[$index]['amount'] += $bank['amount']; 
    } 
} 
print_r($amount); //display 

// for search if a bank has been added into $amount, returns the key (index) 
function bank_exists($bankname, $array) { 
    $result = -1; 
    for($i=0; $i<sizeof($array); $i++) { 
     if ($array[$i]['name'] == $bankname) { 
      $result = $i; 
      break; 
     } 
    } 
    return $result; 
} 

Answer 2

Beispiel in C#:

Dictionary<string,object>[] items = { 
    new Dictionary<string, object> {{ "name", "Bank BRI"}, {"amount", 0 }}, 
    new Dictionary<string, object> {{ "name", "Bank BRI"}, {"amount", 0 }}, 
    new Dictionary<string, object> {{ "name", "Bank BCA"}, {"amount", 1412341234 }}, 
    new Dictionary<string, object> {{ "name", "Bank CIMB Niaga"}, {"amount", 532532552 }} 
}; 

var amounts = new Dictionary<string, int>(); 

foreach (var item in items) { 
    string bank = (string)item["name"]; 
    int amount = (int)item["amount"]; 
    if (amounts.ContainsKey(bank)) { 
    amounts[bank] += amount; 
    } else { 
    amounts.Add(bank, amount); 
    } 
} 

foreach (var amount in amounts) { 
    Console.WriteLine("{0}: {1}", amount.Key, amount.Value); 
} 

Answer 3

$a = arrayofindonesianbanks; 

foreach ($a as $anarrays) { 
     echo "$anarrays[name]." ".$anarrays[amount]"; 
    } 
} 

foreach in PHP zu sehen.

Answer 4

Also, zuerst müssen Sie $amountsArray, um die Werte, die Sie aufgelistet, irgendwie zugewiesen bekommen. Dann gilt:

$bankTotals = array(); 
foreach($amountsArray as $amount) 
{ 
    $bankTotals[$amount['name']] += $amount['amount']; 
} 

Danach wird $bankTotals ist ein Array auf Namen der Bank indiziert, wobei der Wert der Gesamtmenge für die Bank. Sie können dieses Array verwenden, wie Sie von hier sehen.

Eine Sache, die nützlich sein könnte, ist eine andere foreach Schleife sie alle aus drucken:

foreach($bankTotals as $name => $amount) 
{ 
    echo $name.".....".$amount."\n"; 
} 

Answer 5

Ich würde lieber hinzufügen

$bankTotals = array(); 
foreach($amountsArray as $amount) 
{ 
if(isset($bankTotals[$amount['name']])) 
    $bankTotals[$amount['name']] += $amount['amount']; 
else 
    $bankTotals[$amount['name']] = $amount['amount']; 
}
